What are the major components of the GEOTrac system?
• Modem – A hardware device for transmitting digital data over a wireless satellite signal by modulating the data into a digital signal to send it and demodulating an digital signal into data to receive it. • Antenna – hardware device that receives and transmits over-the-air signals to the modem. • Power source – the modem and touch screen terminal requires either an alternating current (AC) or direct current (DC) 12 volt power supply • Mobile Data Terminal (MDT) – for customers requiring text messaging or pre-formatted messages between operators or central dispatch, a small rugged touch screen terminal is available • Satellite and signal – there are two basic types of satellites: • Low Earth Orbit (LEO) and Geostationary. LEO satellites circumnavigate 804 km above the earth at 26,820 km/hr. It takes 100 minutes for these satellites to complete one orbit. A multiple LEO satellite network can provide global coverage. • Geostationary satellites maintain an orbit 37,000 km above the earth
